• Reactivity of diacyloxyiodobenzenes toward trivalent phosphorus nucleophiles
  作者：S?awomir Makowiec、Janusz Rachon

  DOI：10.1002/hc.10161

  日期：——

  equiv of sodium diisopropyl phosphite in THF produces diisopropyl 1-(diisopropoxyphosphinyl)ethylphosphonate with excellent yield. It was found that diacyloxyiodobenzene/PR3 system may serve as an acylating agent; the acylation process can proceed via carboxylic acid anhydride or acylphosphonium salt 17 depending on the protocol used. New very efficient method for synthesis of 2,4,6-trimethylbenzoic

  研究了二酰氧基碘苯和四价磷亲核试剂的反应。已确定，在醇钠存在下，H-膦酸酯和仲氧化膦与二乙酰氧基碘苯在醇中反应，分别生成磷酸三烷基酯和次膦酸烷基酯。对于这种转化反应中间体6被提出。与此相反，在 THF 中用 3 当量的二异丙基亚磷酸钠处理二乙酰氧基碘苯以优异的产率生成 1-（二异丙氧基次膦基）乙基膦酸二异丙基酯。发现二酰氧基碘苯/PR3体系可作为酰化剂；根据所使用的方案，酰化过程可以通过羧酸酐或酰基鏻盐 17 进行。新的非常有效的合成 2,4 的方法，开发了6-三甲基苯甲酸酐。© 2003 Wiley Periodicals, Inc. 杂原子化学 14:352–359, 2003; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.10161

  [二(酰氧基)碘]苯与仲氧化膦或H-次膦酸盐在伯胺或仲胺存在下的反应允许人们在一锅法中获得次膦酸或膦酸酰胺。我们利用强酰化系统 DAIB/R2P(O)H 对胺进行膦酰化。然而，反应机制是多途径的，并且导致次膦酸或膦酸酰胺的产率适中。当胺的浓度低时，分子间过程起主要作用，导致通过混合磷酸-羧酸酐形成羧酰胺，而且在低浓度的胺中，四氢呋喃有效地与胺竞争亲核攻击酰化中间体。© 2009 Wiley Periodicals, Inc. 杂原子化学 20:81–86, 2009; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20514

  phosphinic, and phosphoric monoacids has been developed. Inert pentavalent P(V)-compounds (phosphonate, phosphinate, and phosphate) are activated by triflate anhydride (Tf2O)/pyridine system to form a highly reactive phosphoryl pyridinium intermediate that undergoes nucleophilic substitution with H2O to selectively deprotect one alkoxy group and form organophosphorus monoacids.
